Next, the procedure for mounting the mounting member 7 on the base member 9 will be described with reference to FIGS. 6 to 7 (b). FIG. 6 is a perspective view showing the mounting member 7 and the base member 9. In FIG. 6, a part A of the first unit U1 shown in FIG. 2 is shown. In FIGS. 6 to 7 (b), the third groove portion 59 is omitted for simplification of the drawings.

As shown in FIG. 6, the mounting member 7 is mounted on the base member 9. Then, the claw portion 25 is fitted in the second groove portion 47.

In order to mount the mounting member 7 on the base member 9, the procedure shown in FIGS. 7 (a) and 7 (b) is followed. FIG. 7A is a plan view showing a state before mounting of the mounting member 7. FIG. 7B is a plan view showing a state after mounting the mounting member 7. In addition, in FIG. 7A and FIG. 7B, in order to clarify the drawing, the first recess 41 and a part of the second groove 47 are shown by dot hatching.

As shown in FIG. 7A, the operator tilts the mounting member 7 with respect to the direction PD in a plan view to allow the engaging portion 23 to enter the first recess 41. The plan view indicates that the mounting member 7 and the base member 9 are viewed from a direction orthogonal to the longitudinal direction and the lateral direction of the base member 9. Specifically, the engaging pieces 29b of the pair of engaging portions 23 enter the pair of second recesses 53, respectively. Then, the operator rotates the mounting member 7 in the rotation direction R (clockwise in FIG. 7A).

The mounting member 7 is rotatable from the position where the engaging portion 23 enters the first recess 41 to the position where the engaging portion 23 engages with the first groove portion 43. Specifically, from the position where the pair of engaging pieces 29b of the engaging portion 23 each enter into the pair of second recesses 53, the position where the pair of engaging pieces 29b each engage with the pair of first groove portions 43. Up to, the mounting member 7 is rotatable.

Therefore, as shown in FIGS. 7 (a) and 7 (b), the mounting member 7 is substantially orthogonal to the direction PD from the position where the mounting member 7 is inclined with respect to the direction PD in a plan view. When the operator rotates the mounting member 7 in the rotation direction R to the position, the pair of engaging portions 23 engage with the pair of first groove portions 43, respectively. Specifically, the pair of engaging pieces 29b each engage with the pair of first groove portions 43. As a result, the mounting member 7 is mounted on the base member 9. The mounting member 7 may be mounted on the base member 9 by rotating the mounting member 7 in the direction opposite to the rotation direction R (counterclockwise in FIG. 7A).

Here, in order to further facilitate the understanding of the mounting procedure of the mounting member 7, the procedure before the engaging portion 23 of the mounting member 7 enters the first recess 41 (FIG. 7) with reference to FIG. 7A. The procedure before the procedure shown in (a) will be described. The operator places the mounting member 7 at the mounting position of the mounting member 7 on the base member 9. In the present embodiment, the mounting position is near the end portion of the base member 9 in the longitudinal direction. Specifically, the operator places the mounting member 7 on the base member 9 so that the pair of engaging pieces 29b abut against the pair of edge portions 45 at the mounting position (hereinafter, "mounting"). procedure"). Then, as described above, the operator tilts the mounting member 7 with respect to the direction PD to allow the engaging portion 23 to enter the first recess 41. Note that the operator omits the mounting procedure and moves the mounting member 7 from a position where the mounting member 7 is separated from the base member 9 while tilting the mounting member 7 with respect to the direction PD in a plan view. , The engaging portion 23 may be made to enter the first recess 41.

As described above with reference to FIGS. 7A and 7B, according to the present embodiment, the engaging portion 23 of the mounting member 7 is made to enter the first recess 41 of the base member 9. , The mounting member 7 is mounted on the base member 9 by rotating the mounting member 7. Therefore, the mounting member 7 can be easily mounted on the base member 9 as compared with the case where the mounting member is inserted from the end of the base member and the mounting member is slid. For example, even when the base member 9 extends long along the direction PD, the mounting member 7 can be easily mounted on the base member 9.

Next, the mounting member 7 mounted on the base member 9 will be described with reference to FIGS. 7 (b) and 8. FIG. 8 is a cross-sectional view showing the luminaire 1 and includes a cross section of the first unit U1 along the line VIII-VIII of FIG.

As shown in FIGS. 7B and 8, the first direction D11, the second direction D12, and the third direction D13 are defined. The first direction D11, the second direction D12, and the third direction D13 are orthogonal to each other. The first direction D11 is parallel to the direction PD. The second direction D12 indicates the width direction of the base member 9 (for example, the lateral direction of the base member 9). The third direction D13 indicates a direction orthogonal to the base member 9 (for example, the contact surface 57 of the base member).

As shown in FIGS. 7B and 8, the pair of engaging portions 23 of the mounting member 7 engage with the pair of first groove portions 43 of the base member 9, respectively. Therefore, the mounting member 7 can be mounted on the base member 9 without using a fastener such as a screw. As a result, the number of parts can be reduced as compared with the case where the fastener is used. By reducing the number of parts, the cost of the luminaire 1 can be reduced. Further, the mounting member 7 can be easily mounted on the base member 9 by engaging the engaging portion 23 and the first groove portion 43 without using a tool.

Further, the first groove portion 43 of the base member 9 is recessed along the second direction D12. Then, the engaging portion 23 of the mounting member 7 engages with the first groove portion 43. Therefore, the pair of first groove portions 43 restrict the movement of the mounting member 7 along the third direction D13. As a result, according to the present embodiment, it is possible to suppress the displacement of the mounting member 7 with respect to the specified position. The specified position of the mounting member 7 indicates, for example, the position immediately after mounting the mounting member 7 on the base member 9.

Further, the first groove portion 43 has a substantially tapered shape in cross-sectional view. Therefore, when the mounting member 7 is rotated in the rotation direction R to engage the engaging portion 23 (specifically, the engaging piece 29b) with the first groove portion 43 (FIG. 7A), the engaging portion 23 (Specifically, the engaging piece 29b) can be easily guided to the depth of the first groove portion 43. As a result, according to the present embodiment, the mounting member 7 can be smoothly engaged with the first groove portion 43. Further, since the first groove portion 43 has a substantially tapered shape in cross-sectional view, the engaging portion 23 (specifically, the engaging piece 29b) is a narrow portion (specifically, a narrow portion at the back of the first groove portion 43). It is sandwiched by the pointed part). Therefore, the pair of first groove portions 43 further restricts the movement of the mounting member 7 along the third direction D13, and the movement of the mounting member 7 along the first direction D11 and the movement along the second direction D12. To regulate. As a result, according to the present embodiment, the displacement of the mounting member 7 with respect to the specified position can be further suppressed.

Further, the pair of engaging portions 23 of the mounting member 7 are engaged with the pair of first groove portions 43 of the base member 9. On the other hand, the main body 21 of the mounting member 7 is in contact with the tip 62 of the second groove 47 of the base member 9. The second groove portion 47 projects from the inside to the outside of the first recess 41. That is, the tip portion 62 of the second groove portion 47 projects to the outside of the first recess 41 with respect to the contact surface 57 (FIG. 4 (b)). Therefore, while the pair of engaging portions 23 are engaged with the pair of first groove portions 43, the main body portion 21 is pressed toward the fourth direction D14 by the tip portion 62 of the second groove portion 47. As a result, the pair of engaging pieces 29b are respectively urged on the inner surface of the pair of first groove portions 43 toward the fourth direction D14. When the engaging piece 29b is urged on the inner surface of the first groove portion 43 toward the fourth direction D14, the friction between the engaging piece 29b and the inner surface of the first groove portion 43 increases. As a result, according to the present embodiment, since the movement of the mounting member 7 along the first direction D11 is restricted, the displacement of the mounting member 7 with respect to the specified position can be further suppressed.

The fourth direction D14 is parallel to the third direction D13 and indicates a direction in which the second groove portion 47 protrudes.

Further, a pair of claw portions 25 of the mounting member 7 are fitted into the second groove portion 47 of the base member 9. Therefore, after the mounting member 7 is mounted on the base member 9, it is possible to regulate that the mounting member 7 rotates in the rotation direction R (FIG. 7A) or in the direction opposite to the rotation direction R. As a result, according to the present embodiment, the displacement of the mounting member 7 with respect to the specified position can be further suppressed. Further, the claw portion 25 is fitted into the second groove portion 47 while being pressed against the pair of side wall portions 61 of the second groove portion 47. Therefore, the movement of the mounting member 7 along the first direction D11 is further restricted. As a result, according to the present embodiment, the displacement of the mounting member 7 with respect to the specified position can be further suppressed. In order for the claw portions 25 to be satisfactorily pressed against the pair of side wall portions 61, it is preferable that the width dimension of the claw portions 25 is slightly larger than the minimum gap dimension of the pair of side wall portions 61.

In particular, the claw portion 25 is bent toward the protruding side of the engaging portion 23 with respect to the main body portion 21. Therefore, it is possible to restrict the mounting member 7 from rotating in the rotation direction R or the direction opposite to the rotation direction R after the claw portion 25 is fitted into the second groove portion 47. As a result, according to the present embodiment, it is possible to prevent the claw portion 25 from coming off from the second groove portion 47.

After fitting the claw portion 25 into the second groove portion 47 (see FIG. 7B), a tool (for example, a flat-blade screwdriver) is used to move the claw portion 25 toward the inside of the second groove portion 47. It can also be pushed further to insert the claw portion 25 deeply into the second groove portion 47. In this case, since the claw portion 25 is plastically deformed, the claw portion 25 is held in a state of being deeply inserted into the second groove portion 47. Therefore, it is possible to further restrict the mounting member 7 from rotating in the rotation direction R or the direction opposite to the rotation direction R. As a result, it is possible to further prevent the mounting member 7 from coming off the base member 9.

Further, the side wall portion 61 of the second groove portion 47 of the base member 9 is curved and has an inner curved surface and an outer curved surface. Therefore, when the mounting member 7 is rotated in the rotation direction R to fit the claw portion 25 into the second groove portion 47 (FIG. 7A), the claw portion 25 slides along the outer curved surface of the side wall portion 61. Move. As a result, according to the present embodiment, the claw portion 25 can be smoothly fitted into the second groove portion 47.

Further, the main body 21 of the mounting member 7 is in contact with the pair of contact surfaces 57 of the base member 9. Therefore, according to the present embodiment, the mounting member 7 can be stably mounted on the base member 9.

Further, a third groove 59 is formed on each of the contact surfaces 57 of the base member 9. Therefore, when the mounting member 7 is rotated in the rotation direction R to mount the mounting member 7 on the base member 9 (FIG. 7A), the mounting member 7 has a third groove 59 as compared with the case where the mounting member 7 does not have the third groove 59. Friction between the main body 21 and the contact surface 57 can be reduced. As a result, according to the present embodiment, the mounting member 7 can be smoothly mounted on the base member 9.

Further, the pair of first holding portions 49 of the mounting member 7 holds the cover member 5. Therefore, according to the present embodiment, it is not required to provide a dedicated member for holding the cover member 5, so that the number of parts can be further reduced.

Further, the pair of second holding portions 51 of the mounting member 7 hold the light emitting module 3. Therefore, according to the present embodiment, it is not required to provide a dedicated member for holding the light emitting module 3, so that the number of parts can be further reduced.

The light emitting module 3 includes a substrate 71 and a plurality of light emitting elements 72. The plurality of light emitting elements 72 are mounted on the substrate 71. Then, both side portions of the substrate 71 are held by a pair of second holding portions 51, respectively. Each of the light emitting elements 72 is, for example, an LED. The plurality of light emitting elements 72 face the inner surface of the cover member 5 and emit light toward the inner surface of the cover member 5. As a result, the light is emitted to the outside of the luminaire 1 through the cover member 5. The light emitting module 3 may include a single light emitting element 72.

As described above with reference to FIG. 8, the mounting member 7 is mounted on the base member 9, and the base member 9 further holds the cover member 5 and the light emitting module 3. As a result, the first unit U1 is configured. Further, according to the present embodiment, the engaging portion 23 and the claw portion 25 of the mounting member 7 and the first groove portion 43 and the second groove portion 47 of the base member 9 make the mounting member 7 without using a fastener. Can be fixed to the base member 9.

Subsequently, the first unit U1 attached to the second unit U2 will be described with reference to FIG. The pair of elastic portions 27 of the mounting member 7 of the first unit U1 fit into the inner 12 of the housing 10 of the second unit U2. Therefore, each of the pair of elastic portions 27 abuts on the pair of inner wall surfaces 75 of the housing 10. Since the pair of elastic portions 27 have elasticity, an urging force acts from the elastic portions 27 toward the inner wall surface 75. As a result, the first unit U1 is attached to the second unit U2. The pair of inner wall surfaces 75 face each other.

(Modification example)
The lighting fixture 1A according to the modified example of the present embodiment will be described with reference to FIG. The luminaire 1A according to the modified example is mainly different from the luminaire 1 according to the present embodiment described with reference to FIGS. 1 to 8 in that the second unit U2 has the mounting member 7 and the base member 9A. Other configurations of the luminaire 1A are the same as the configuration of the luminaire 1. Hereinafter, the difference between the luminaire 1A according to the modified example and the luminaire 1 according to the present embodiment will be mainly described.

FIG. 9 is a cross-sectional view showing the luminaire 1A. As shown in FIG. 9, the luminaire 1A includes a base member 9A in place of the base member 9 (FIG. 8) of the luminaire 1. The base member 9A is different from the base member 9 in that it does not have the first holding portion 49 and the second holding portion 51. Other configurations of the base member 9A are the same as those of the base member 9.

The mounting member 7 is mounted on the base member 9A in the same manner as in the present embodiment described with reference to FIGS. 6 to 8. Then, the base member 9A is held in the housing 10. As a result, the second unit U2 is configured.

On the other hand, the first unit U1 includes a housing 90. The housing 90 holds the light emitting module 3 and the cover member 5 that covers the light emitting module 3. As a result, the first unit U1 is configured.

The pair of elastic portions 27 of the mounting member 7 of the second unit U2 fit into the inner 92 of the housing 90 of the first unit U1. Therefore, each of the pair of elastic portions 27 abuts on the pair of inner wall surfaces 91 of the housing 90. Since the pair of elastic portions 27 have elasticity, an urging force acts from the elastic portions 27 toward the inner wall surface 91. As a result, the first unit U1 is attached to the second unit U2. The pair of inner wall surfaces 91 face each other.

As described above with reference to FIG. 9, the configurations of the mounting member 7 and the base member 9A according to the modified example are the same as the configurations of the mounting member 7 and the base member 9 of the present embodiment, respectively. Therefore, in the modified example, the mounting member 7 can be mounted on the base member 9A without using a fastener, as in the present embodiment.
